Jumbo OLED Fun

A few days back, a discussion on the Apple II Facebook group asked about large format Floppy Emu displays for people with vision difficulties. Here’s a 2.42 inch OLED that’s a simple drop-in replacement for the OLED in Floppy Emu Model C. With more than 3x the screen area of the standard OLED, that’s a big increase in display size!

This particular OLED was $17.99 and can be purchased here. The only minor issue is that the rightmost column of pixels appears on the left side of the display – some sort of off-by-one error.

    Wow! That looks great. A little expensive, but really looks wonderful!

    Is there a firmware fix for the ‘off by one’ pixel issue? perhaps a ‘big screen firmware’? that would be great. Thanks!

    There is no simple “fix”, but I sent you a one-off firmware version that draws correctly on the jumbo LED shown here. It won’t work on the normal size OLED. Displays with different sizes may also use different controller chips, which require different commands and addressing to update the display. The display is a write-only device, so unfortunately there’s no way to query it to see what controller is present.

    Hi Steve – Can you send me a copy of that one-off firmware version for the jumbo LED? Thanks. Ken

    Sorry for the necropost. Looks like the price has come down for the jumbo display. Should it be configured for I2C or SPI?

  9. Steve - October 15th, 2023 10:24 am

    It’s SPI. The latest firmware supports this as an option in the settings menu.

    I tried this OLED Display from Amazon

    but it doesn’t seem to work — the screen turns on for a moment to display the start up image, then goes dark. Has anyone seen that issue?
